Coke anodes are made of Calcined Petroleum Coke, recycled anode butts, and coal-tar pitch (binder). The anodes are manufactured by mixing aggregates with coal tar pitch to form a paste with a doughy consistency. This material is most often vibro-compacted but in some plants pressed. The green anode is then sintered at 1100–1200 °C for 300–400 hours, without graphitization, to increase its strength through decomposition and carbonization of the binder. Higher baking temperatures increase the mechanical properties and thermal conductivity, and decrease the air and CO2 reactivity.
The specific electrical resistance of the coke-type anodes is higher than that of the graphitized ones, but they have higher compressive strength and lower porosity.

The Hall-Héroult electrolysis process is the major production route for primary aluminium. We makes prebaked anodes for aluminium smelters.
We manufacture carbon anodes for aluminium smelters.

Prebaked Anodes are also made of Petroleum Coke, mixed with coal-tar-pitch, followed by forming and baking at elevated temperatures.

Our Prebaked Carbon Anodes blocks has been exporting to Russia, United Arab emirates, United States, kazakhstan, India, Sweden, Germany, Canada, Switzerland, Malaysia, Iceland, Nigeria, Nigeria, Norway, Netherlands, Azerbaijan...

Anual Production Capacity of 150,000MT.

Prebaked Consumable Carbon Anodes are a specific type of anode designed for aluminium smelting using the Hall-Héroult process.

CarboGraphite offers high density, Low Electrical Resistance prebaked carbon anode blocks for Aluminium Smelting Industry.

Pre-baked Carbon anode is made from the qualified petroleum coke and coal tar pitch through advanced technological process including mixing, vibrating and press forming, high-temperature baking process.

We can supply Pre-baked Carbon Anode for aluminium electrolysis,and design and manufacture according to customer's requirements. This product has features of low ash, low electrical receptivity and high strength

Pre-baked Anode for aluminum electrolysis (code name TY) is the conductive electricity anode in aluminum electrobath , compared with self-baked anode paste it has more advantages such as no asphalt fume pollution, better working conditions, low power consumption and so on . The roles of pre-baked anode in aluminum electrobath are, first as a conductive electrode; second, to participate in the electrochemical process of alumina.
